soft bristle brush, (i.e. an old toothbrush).

enlarge the screen openings.

If the spider/insect screen becomes damaged or cannot be cleaned, call Ducane Cus-
tomer Service at 1-800-382-2637 for replacement parts.
To reassemble, reverse steps 2 through 5.

Cleaning the Spider/Insect Screens

Your Ducane

gas barbecue, as well as any outdoor gas appliance, is a target for spiders

and other insects. They can nest in the venturi section (1) of the burner tubes. This
blocks the normal gas fl ow, and can cause the gas to fl ow back out the air shutter. This
could result in a fi re in and around the air shutters, under the control panel, causing
serious damage to your barbecue.
The burner tube air shutter is fi tted with a stainless steel screen (2) to prevent spiders
and other insects access to the burner tubes througth the air shutter openings.
We recommend that you inspect the Spider/Insect screens at least once a year. Also,
inspect and clean the Spider/Insect screens if any ot the following symptoms occur:

1. The smell of gas in conjunction with the burner fl ames appearing yellow and lazy.
2. Barbecue does not reach temperature.
3. Barbecue does not heat evenly.
4. One or more of the burners do not ignite.

ƽ DANGER: Failure to correct the above mentioned symptoms

may result in a fire, which can cause serious bodily injury or
death, and cause damage to property.
